COMBINATION CORN CRIBy AND GRAIN BIN.

Application filedv October 27, 1924. Serial No.'746,184. v

ily invention hasto do with bins or cribs for holding grains, such for instance, corn,;

oats, wheat, barley, etc. Y n

The purpose of my invention is to provide such a bin, which can be. constructed simply Y and easily and which would rbe very durable and require a minimum of repairs, and which can Abe used for the storage ot corn in the ear, shelled corn, or small grain, as wheat, barley, etc., without any change in structure. A further object isto provide such a grain bin having certain ,advantages of structure, which contribute to securing a satisfactory '..izontally corrugated metal, a portionof one Vfith theseI and other objects in view, my

invention consists in the construction, ar-

rangement and combination of the various] parts of my device in the location, shape,

size, form and frequency ofthe openings for ventilation in the side walls of the crib or bin andin the main and Vsecondary pipes or Ventilating shafts andl in a. sliding `sleeve 'or the main Ventilating .pipe or shaft, where-v by .the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated'in the accompanyiiig drawings, in which:

system.

Figure 6 is a sectional View taken on .the line 46 6 ot Figure 5.

In the accompanying drawings, I have .used .the reference numeral 10 to indicate generally the baseer foundation upon which' my improved bin rests. For this purpose, have preferably used a concrete floor slab which serves both as a foundation and a floor and may, if desired, be covered with 'gal-i.

the Ventilating system as may beineeded or desired, accordingfto the size and. shape of the bin, may be employed.

.The binitself may begof any desired shape lor size.

For purposesof illustrating Vmy iiivention, I have shown a round bin with a tapered cone shaped top. f

. It is my purpose to providea bin having walls such that thestructure may. be used for. storing vsmall grain: such as yoats or `wheat, or for storing corn, Whether shelled or oiithe cob, or as a general storage room.

l, thereiore, build my walls of strips-of horof thesestripsl have shown somewhat `in detail in Figures-5 and 6. y l

The strip is` indicatedI by the Areference character` 11, vand itis .provided with the regularly placed horizontal corrugations 12,

which in a round --tank are: preferably arvided and a movable window'or door device 16 may alsobe provided for the wallof the bin, the structure 16y being arranged just below the eve of thebin roof.

.The metal of the strips 11 is preferably galvanized iron orother material of such character` and so treated as to resist rust.

1 vThe .bin is vpreferably providedl with a sheet metal conical cover 17, having at yits apex an. opening, and central .sleeve 18.

The corrugations 12serve the important function of strengtheningthe wall of the. bin. They also lmake' possible another important feature of my structure. It is well known that itis highly desirablethat the air .should have free access toV any storedgrain.

lnforder toprovide for a free circulation Voit air through the walls' of my bin, I vpreferably providein the lower overhanging portions of each corrugati'onlQ, a series of rows of openingsil) Lformed by cutting the metal on three sides of'tongues 20leaving Lthe tongues .attached at their lower` edges.

These tongues are.I then forced inwardly at their upper portions, 4as-clearly illustrated in Figures 5 and;

Thel g openings` 19 yafford free lpassage for air for permitting the circulation thereof within the bin.

Being arranged below the centers of the corrugations and in the underhanging portions thereof, water will flow downwardly and past the openings 19 on the outside of the bin, but will not iiow through the walls to the interior of the bin.

The holes 19 and tongues 2O are of suchv size and shape and so arranged that they will not permit the escape of wheat or other small grain. It is desirable that the grain should be aerated at points inwardly Vtrom the walls of the bin, and for accomplishing 'circulation of air at pointsinwardly from the walls, 1 have provided the following means. f

Extending through the sleeve 18 is a pipe .21', which projects downwardly into the binl stand, is provided with numerous openings similar to the openings 19, except that they are shorter horizontally, outwardly and downwardly projecting tongues 26 similar to the tongues v20.

At the bottom of the pipe 21 are larger openings 27 (see Figure at their upper 'portions having overhanging lips 28.

Extending away from the bottom of the pipes 21 radially are pipes 29, closed at their .outer ends and having at their inner ends at their upper portions, projecting lips 30 adapted to cooperate with the lips 28 so that the pipes 29'can be tilted for inserting the lips 30 under the lips 28 and then swung I downwardly to horizontal position, as illustrated in Figure 2, where theywill be held in position registering with the openings 27 against accidental removal.

The pipes 29 are so connected with the pipe'21 as to permit them to be lifted out of the wayk tor shoveling the grain from the` iioor of the bin and for cleaning the floor of the bin.

The upper portions of the pipe 29 and the outer ends are closed, but at the sides of the pipe 29 rows of holes 31, similar to the holes 19, are cut therein and tongues 32 are'pressed.

outwardly so .as to stand outwardly and downwardly.

1t will thus be seen that air can circulate freely through the wall ot the bin and through the pipes 29 to and through the pipe 21. The use oi the pipe 21 creates a ,draft ordrawing the air through the grain and the pipes 29 and through the perforated` wall ot the lower part of the pipe 21 for forcing a circulation.

1 find that where the level of the grain in the bin is lowered substantially below the upper row of tongues 26, the air will pass outwardly through the upper openings 25 into the upper empty part o'r' the bin and the drait .eiect of the upper iinperforate part t the pipe 21 is largely lost.

1n order to maintain effectiveness of the pipe 21 for insuring a dratt upwardly through the center ot the bin, I have provided tor the upper part of the pipe 21, a sliding outside sleeve 33, shown in Figure 2.

The sleeve has its upper and lower ends slightly bell shaped, as at 34.

@n the vsleeve 33 are brackets 8,5 to which are secured ropesor the like 36 eX- tending upwardly and over pulleys 37 supported from the top 17. y

rllhe ropes no Athen converge, as at 38. (Figure l) andare connectedwith a single rope extending to a point outside the` bin and over a pulley i0 and thence downwardly through a fastening device 41 outside the bin 1 li/"Jlieii the binis practicallyfull of grain,

the sleeve is held in its upper position till` part oi the grain iii the bin is removed. The sleeve 33 may then be lowered over the upper exposed holes 25 so as to keep its lower end in the grain and thus insuring the upward draft of air in the pipe instead ot permitting air to escape through the lupper holes 25 into the upper par-tot the bin. y

it will be seen from the foregoing, that I have provided a grain bin ci simple and very durable construct-ion.v rlhis bin can be readily and easily manufactured or built largely ii-oin corrugated sheet metal. llhen completed, the walls are amply strong enough tor the purpose, and are provided with periorations, which permit tree circulation of air therethrough. Y

t should be mentioned, that the walls in square or oblong bins are to be suitably re` inforced or braced as with angle or T irons set upright against the walls at intervals of from three to tour feet and connected across the bin with tie rods.

The openings 19 in the corrugated wall plates 11 are so made that no..mice, rats orV squirrelsor the like can get into the bin through them. y

rlhe openings 19in the corrugated plates 11 are so made and arranged that the upper part of the corrugations 12 forms a part of the water shed and the lip 2O being cut with the corners slightly rounded and the upper .edge being iforced slightly inward completes the water shed so bin.

rlhe openings 19 are made of such size that no grain such as wheat, barley, etc., can

pass through.

. rllhe openings form and frequency that sufficient air will that no water can enter the imr 19, are made otsuch size,

be admitted to the bin that allgrains stored therein will be thoroughly aerated and cured, or preserved.

The arrangement of the openings 19 in the side plates 11, and the openings 25 in the pipe 21, and the openings 31 in the pipes 29 and the wall plates 11 and the pipes 21 and 29 is such that a forced circulation of air through grain stored in the bin is assured at all times.

The arrangement of the wall plates and the pipes 21 and 29 andthe openings in them as stated above, is suchthat the air enters the bin through the openings 19 in the wall plates 11, passes through the grain and through the openings 25, in the Ventilating pipe 21 and the openings 31 in the secondary ventilatino` pipes 29 in to the pipes 29 and 21 and on through them out of the bin through the screen 22 to the open air. i

The circulation herein described is such that should the grain stored'in the bin develop any heat at any time an increased circulation would be developed as warm air tends to rise through the course of least resistance thereby creating a natural draft along the course herein described, thereby drying and curing the grain stored in the bin. V Y

lVhen the level of the grain in the bin is lowered, the sleeve 33 may be correspondingly lowered. Y i

IW hen it is desired to clean out the bin, the pipes 29 can be swung upwardly at their outer ends until the lips 30 clearthe lips 28 whereupon the pipes 29 may be moved out of the way. v

Changes may be made in the details and `tending outwardly and downwardly structure and arrangement of wparts of my improved grainvbin without departing from the real spirit and purpose of my invention,
